There is little debate Vasyl Lomachenko is one of the top fighters in boxing today.

Some believe he may be the best fighter. Period.

Longtime boxing promoter Bob Arum has said he has never seen a fighter as talented as Lomachenko. That says a lot, considering Arum has promoted Muhammad Ali, "Sugar" Ray Leonard, Oscar De La Hoya, Floyd Mayweather Jr. and Manny Pacquiao.

Lomachenko believes he still has a lot to prove.

"I haven't fought the best fighters in my division yet," said Lomachenko.

While he awaits a fight against a belt-holder in the junior lightweight division, Lomachenko will display his talented skills on Aug. 5, when he squares off against two-time world title challenger Miguel Marriaga at the Microsoft Theatre (formerly the Nokia Theatre) in Los Angeles.

The 12-round bout will air live on ESPN at 7 p.m.

The telecast will mark the second time ESPN will air a Top Rank card under a multiyear deal. The first broadcast was July 1, when Jeff Horn won the WBO welterweight title with an upset decision over Pacquiao before a crowd of more than 50,000 in Brisbane, Australia.

Lomachenko's fight against Marriaga could not come at a better time, according to Arum. He believes the ESPN telecast will create a platform for Lomachenko to showcase his talents to casual fans.

Lomachenko (8-1, 6 knockouts), who lives and trains in Oxnard, has had all but one of his bouts on HBO broadcasts.

The two-time Olympic gold medalist is coming off a one-sided knockout win over Jason Sosa on April 8 in Oxon Hill, Maryland. He has won his last five bouts by knockout.

The southpaw Lomachenko is expected to win on Aug. 5, but he has expressed his frustration that some of the top fighters in the division won't face him. Three fighters — Gervonta Davis, Miguel Berchelt and Jezreel Corrales — hold a world title at 130 pounds and Lomachenko is eager to fight any of them.

"I want to face those fighters because I believe they will bring out the best in me," said Lomachenko. "Until then, how can I say I'm the best when I have not fought the best fighters in my division?"

Lomachenko has said he wants to face WBC World lightweight titleholder and Oxnard native Mikey Garcia. That fight may have to wait until later this year or 2018 as Garcia has a fight lined up against Adrien Broner on July 29 at the Barclays Center in Brooklyn, New York.

Former world title contender Romulo Koasicha (25-6, 15 KOs) will face Josue Veraza (18-8-1, 14 KOs) in a 10-round featherweight bout Friday night at the Auditorio Blackberry in Mexico City. Telemundo will air the fight at 11:35 p.m.

In a battle of unbeaten junior welterweights, Ivan Baranchyk (16-0, 10 KOs) will face Keenan Smith (11-0, 5 KOs) in a 10-round bout Friday night at the Buffalo Run Casino in Miami, Oklahoma. The fight will headline a four-bout Showtime telecast beginning at 7 p.m.
